This paper reports the results of exploratory research to develop a pilot pattern language for systems engineers at BAE SYSTEMS. The pattern language was designed to encapsulate knowledge about possible trade-offs made by systems engineers about architecture designs that satisfied different system requirements for submarine manoeuvring systems. Our intention is that this knowledge can be reused...

This paper investigates the impact of the US and China’s foreign aids to Africa on trade flows between donor and recipient countries. Evidence from the gravity model estimates reveals that the two donors’ exports are strengthened by their aids to African partners. Interestingly, China’s aid shows a positive effect on its total volume of trade and imports from Africa, while the aid from the US e...

Understanding the dynamics of reciprocation is of great interest in sociology and computational social science. The recent growth of Massively Multi-player Online Games (MMOGs) has provided unprecedented access to large-scale data which enables us to study such complex human behavior in a more systematic manner. In this paper, we consider three different networks in the EverQuest2 game: chat, t...

The Heckscher-Ohlin-Vanek (HOV) theorem predicts whether a country will be a net exporter of services of a certain factor and the volume of the factor content of trade given the country's and the world's factor endowment information. Recent empirical work has documented that the measured factor content of trade is too small compared to the theoretical prediction and named this special pattern o...

This paper is concerned with the Trade Policy Review Mechanism (TPRM), an important policy review function of the WTO. From a developing country perspective, a truly effective TPRM should accomplish several interrelated goals which together should add up to a boost to investor confidence in developing country markets. Several improvements that may move us closer to such a regime are discussed. ...

We explore the consequences of placing the Standard Model gauge fields in the bulk of the recently proposed localized gravity model of Randall and Sundrum. We find that the Kaluza Klein excitations of these fields are necessarily strongly coupled and we demonstrate that current precision electroweak data constrain the lowest states to lie above ' 23 TeV. Taking the weak scale to be ∼ 1 TeV, the...

1. South Africa: Summary of faultlines and action points

We offer a new perspective to the unionised wage effects of unilateral trade liberalisation by considering endogenous domestic market structure. Hence, in contrast to the existing works, which focus on the short-run effects of trade liberalisation on unionised wage, we focus on more long-run effects by considering the effects of trade liberalisation on the domestic market structure. Trade liber...
